14 Claims.

The invention relates especially to that type of comber in which anipper moving forward and backward has associated with it a pair of detaching rolls which assist in detaching a combed tuft of fibres from thelap borne by the nipper and piecing it to the end of the web alreadycombed. During this operation the detaching rolls have a progressiveforward and reverse movement. The forward movement of the rolls assistsin the detachment of the combed tuft from the lap at the same timeefiecting the piecing up operation and advancing the combed web in adeterminate amount. The reverse movement of the detaching rolls, thenfollowing, returns the combed web for its end to receive the combedfringe of lap laid upon it by the forward movement of the nip-perpreliminary to the next piecing up operation.

Difficulties are encountered in the effective operation of the comber inaccordance with the principles above outlined in that the body of thecombed web is oftentimes not uniform in thickness and curled strands offibre appear in it, these differences being aggravated more or less bythe character of the staple Worked upon,

The difliculties above referred to arise primarily from the character ofthe combed tuft detached from the lap and added to the end of the combedweb. This tuft presents a body portion in thickness substantially equalto the thickness of the combed web. As approach is made to the freefront and rear ends of the tuft, however, the thickness of the tuft isgradually lessened, the extreme free ends of the tuft both terminatingin finely drawn out filaments.

Accordingly in order to obtain substantial uniformity in the thicknessof the combed web the contracted fore end portion of the tuft should beapplied and pieced to the contracted rear end portion of the combed webwhich is the contracted rear end portion of the tuft last applied.

Curls occur in some of the fibres of the combed web for the reason thatafter piecing up operation the detaching rolls advance the combed web sofar that the contracted rear end of the tuft last pieced to the web isbrought into the bite of the rolls, sometimes only a relatively fewfilaments of the fibres remaining between the rolls. In consequence uponthe reverse movement of the rolls, the. top roll having been moved backover the bottom roll in the operation of the machine, the fibres leftbetween the rolls will tend to follow the top roll and curl around it.Accordingly when the detaching rolls are again advanced curls willappear in the combed web. This difiiculty I have found may be overcomeif at the termination of the forward movement of the detaching rolls thebody of the web is left in the bite of the rolls. Accordingly forovercoming this difliculty of curls in the combed web as well as forobtaining such piecing up as will effect uniformity of thickness in thebody of the web, it is necessary that the detaching rolls have a preciseforward and reverse movement properly relationed, and that the movementsshall vary dependent upon the character of staple worked upon.

The objects of my invention are accordingly as follows:

1. That the machine may deliver a combed web or sliver having uniformityof body.

2. That the fibres in the combed web or sliver thus delivered shall befree from curls.

3. That a precise forward and reverse movement shall be given thedetaching rolls and in timed relationship to the other operating partsof the machine.

4. That unnecessary excess motion in the detaching rolls shall beeliminated and to this extent preventing wear upon the rolls, especiallythe leather covered top roll.

5. That both the forward and reverse movement given the detaching rollsshall be a precisely adjusted movement, and in which the relative extentof movement forward and reverse shall be evident to the operator by anindicator.

For purposes of illustration the invention is described as applied to acomber shown in the Tunstall Patents No. 1,351,076 of August 13, 1920and No. 1,394,054 of October 18, 1921, such portions only of the machinebeing shown as are necessary for a proper understanding of theinvention.

I and 2 are the front bottom and top detaching rollers, respectively. 3and 4 are the back bottom and top detaching rollers, respectively. Theback top detaching roller 4 is moved forward and backward around theaxis of the back bottom roller 3 in the usual manner during theoperation of the machine by mechanism not shown. The rollers aresuitably supported in bearings on the machine.

The front and back bottom detaching rollers I and 3 are driven rollers,the roller I having a pinion 5 on its driven end, the roller 3 having apinion 6 on its driven end. These pinions are in mesh with an idler I.In mesh with the pinion 6 is a gear 8 for driving the rollers 3. The motion thus applied to the pinion 6 by the gear is transmitted to thepinion 5 for driving the roller I by the idler 1. Thus both rollers Iand 3 will be operated by the gear 8 to turn simultaneously in the samedirection.

The gear 8 is turned by a roller motion 9. This motion is driven by astud ID in a revolving disk II through a rigid connecting link I2. Thedisk II is arranged upon a shaft I3 having bearing to turn on an uprightI5 forming a part of the frame of the machine. The shaft I3 is turned bya gear I6. This gear is constantly, in mesh through intermediategearing, not shown, with the main driving shaft of the machine, andaccordingly through mechanism, not shown, may receive a change in timingwith relation to the rest of the machine.

The roller motion 9 comprises spaced cheeks I8, I9 rigidly connected bypins 20. Arranged within the cage formed by these cheeks, and mounted toturn on a shaft 22, is a ratchet 23 having a hub 24' to which the gear 8is keyed. The cheek I8 is mounted to turn freely upon this same hub.Arranged also within the cage formed by the cheeks and mounted on theshaft 22 is a pawl controlling disk 25 having a hub 26 upon which thecheek I9 is mounted to turn freely. The hub 26 is keyed to the shaft 22.Pivotally mounted on one of the pins 20 connecting the cheeks is a pawl21 (see Fig. 5) having a toothed end 28 for engaging and operating theratchet. In this connection it will be noted that the pawl bears squaredteeth adapted to fit into similarly squared indentations or apertures inthe periphery of the ratchet by which means the pawl will be enabled tomove the ratchet in reverse directions when in engagement therewith. Thetoothed end of the pawl also preferably bears a plurality of teeth forengaging the ratchet in order that a maximum amount of strength may besecured between the teeth on the pawl and the notched end of the ratchetbut still enabling the notches in the ratchet to be made relatively neartogether so securing quick engagement between the pawl and ratchet whenthe pawl is allowed to have engagement therewith. Fixedly connected tothe pawl is an arm 29 bearing upon its end a wheeled follower 30arranged to have bearing against the peripheral edge of the pawladjusting disk 25. This disk presents edge surfaces 3I and 32 located atdifferent distances radially from the axial center of the disk or sothat when the follower 30 is in engagement with the edge surface SI ofthe disk the toothed end of the pawl will be lifted out of engagementwith the ratchet, and when the follower is in engagement with the edgesurface 32 of the disk the pawl will be allowed to have engagement withthe ratchet for operating it. The

follower 30 is maintained in constant engagement with the peripheraledge of the disk 25 by a spring 33 coiled upon the pin on which the pawlis mounted with one end fixed to one of the cheeks and the other end ofthe spring bearing against the arm 29 carrying the follower.

With the parts of the roller motion thus arranged the ratchet 23 will bemoved by the pawl in reverse directions. The direction of such movementwill depend upon the direction of oscillatory movement given the cage bythe operation of the driving disk II through the connecting link I2. Thetime and extent of such movement will depend upon the turned, locatedposition of the pawl adjusting disk 25 which allows the teeth of thepawl to have engagement with the ratchet or lifts them into adisengaging position with relation to it. The driving disk II locatedbelow the roller motion, and continuously turning in a clockwisedirection as indicated by the arrow thereon, imparts to the link I2 areciprocatory up and down movement and the end of the link is pivotallyconnected by a pin 34 to the cheeks of the cage in manner whereby as thelink moves upwardly the cage will be turned in a clockwise direction,and as the link moves downwardly the cage will be turned in a reverse oranti-clockwise direction.

As explained above, the time and extent of movement of the ratchet ineither direction will depend in part upon the turned position of thepawl adjusting disk 25. For turning the disk and thereby positioning itan arm 35 is arranged upon the end of the shaft 22 to which the hub 26of the disk is keyed. This arm extends upwardly at right angles to theshaft. The precise direction and extent of movement given the disk 25 atany timed interval, the time of such movement, and the stationarylocated position of the disk at the termination of such movement for anyinterval of time will depend upon the. control of the arm 35 fixedlycoupled as it is to the disk'through the shaft and intervening hub.

Connecting with the arm 35 is a sliding carriage 36 having as its foreend portion an arm 31 and back of this arm a. forked rear end portion 31The forward end of the arm 31 is pivotally but fixedly secured to thearm 35 at any one of a variety of adjusted positions away from the innerend of the arm or axis of the shaft 22 on which the arm is mounted. Tothis end the arm 35 has a longitudinal slot 38 in it and the end of thearm 31 connects with the arm 35 by means of a fastening clamp 39 passingthrough this slot when the two arms become pivotally connected ontightening the clamp. The arm 31 is made in separate parts 40 and 4|with end portions lapping by one another and slidably fitted one to theother by a tongue 42 on one part'fitting within a groove 43 in the otherpart in order that the arm may be lengthened or shortened. Theoverlapping portions of the respective parts of the arm are providedwith a longitudinal slot 44 and passed through this slot is a clampingstud 45 which, when tightened, locks together the separate parts of thearm in any adjusted position for lengthening or shortening it. In orderthat the lengthening or shortening of the arm 31 may be obtained with anexact nicety the part 40 of the arm is provided upon its side with astud 46 within which is arranged to turn an adjusting screw 41 whichenters a stud 48 formed on the side of the other part M of the arm 31 orside of the carriage 36. By turning this screw with forward or reversemovement the precise adjustment of the armas-to length is secured afterwhich the separate parts of the arm may be locked together on tighteningthe clamp stud 45 as aforesaid. The forked rear end portion 31 of thecarriage 36 extends inwardly to embrace and slide upon a sleeve 50loosely arranged upon a rotary shaft 5|. This sleeve is provided ateither side with annular flanges 52 against which the fork bearslaterally and is thereby prevented from lateral displacement as itslides upon the sleeve. Fixedly secured to the shaft 5| alongside thesleeve 5|] is an eccentric 53 presenting a fore end portion 54 theextremity of which has considerable extension from the center of theshaft 5| on which the eccentric is mounted, and a rear end portion 55the extremity of which has relatively but little extension from thecenter of the shaft on which the eccentric is mounted. Located forwardof the eccentric on the side of the carriage is a wheel 56 with whichthe eccentric has engagement. The carriage 36 is maintained in anormally retracted position by means of a spring 51 in consequence ofwhich, as the eccentric is turned by the rotation of the shaft 5|, thecarriage 36 and arm 35 to which the end of the carriage is secured willbe moved forward as the fore end portion 54 of the eccentric is turnedto engage the wheel on the carriage, and the carriage and arm then movedback by the action of the spring until the wheel on the carriage engagesthe end portion 55 of the eccentric acting as a stop for defining theretracted position of the carriage and arm. In other words, thearrangement is such that the carriage 36 and arm 35 moved by it will bereciprocated as the eccentric is turned by the turning of the shaft 5|on which the eccentric is mounted. Arrangement is made whereby thereturn movement of the carriage obtained by the action of the spring 51may be shortened before the wheel 56 on the carriage engages theextremity of the end portion 55 of the eccentric during the turningthereof, this by a screw 58 on the side of the carriage which engages astop 59 on the upright |5.

The rotary shaft 5| on which the eccentric 53 is mounted has bearing toturn on the upright I5 and is turned in timed relation to the rest ofthe machine by a gear 6| on said shaft, which is one of the gears of themachine operating other parts and is itself turned by gearing from themain shaft.

The outer end of the arm 35 forming a pointer moves across the face ofan indicator 63 having a scale 64 with indications running in oppositedirections from a common center. The indicator is fixed to the uprightl5. The indicator according to the indication on the scale as designatedby the pointer indicates the. relative movement in reverse directions ofthe arm 35 and accordingly that of the pawl controlling disk 25 whichhas the same movement as the arm. The zero point on the scale and fromwhich the scale runs in opposite directions is an assumed point abouthalf way between the extremes of movement in forward and reversedirections of the arm.

The mechanism above described is applicable to a double sided comber aswell as a single sided comber. In the case of the double sided comberthere will be two of the gears 6| in mesh arranged on separate shafts 5|and turning in reverse directions and accordingly the mechanismsoperated by them respectively will be op erating in reverse directionsone to the other. In the case also of the double sided comber the spring51 which effects a return of the carriage upon the termination of itsforwardmovement by the eccentric is interposed between and. attached toseparate carriages 36 on the respective sides of the comberas shown inFig. 5.

The'operation is as follows: The rotation of the driving disk II willimpart through thelink |2 a forward and reverse oscillatory movement tothe cage which carries the pawl 21 for operating the ratchet 23. Thecage is turned for,- ward in a clockwise direction .as the link movesupwardly, and in a reverse or anti-clockwise direction as the link movesdownwardly. As the link moves downwardly, assuming the pawl is inengagement with the ratchet the ratchet will be turned in ananti-clockwise direction the same as the cage, thereby turning the gear8 mounted on the hub of the cage in the same. anti-clockwise direction.The gear 8 in turn will through the pinion 6, idler and pinion 5 turnthe front and back bottom detaching rollers l and 3 in a forwarddirection or in a direction to deliver or feed the combed web or sliverthen lying between these rollers and their co-operating top rollers. Onthe termination of the downward movement of the link |2 the continuedoperation of the driving disk will move the link upwardly thereuponreversing the movement of the cage to move in a clockwise direction,and, assuming the pawl to bein engagement with the ratchet, the gear 8through the pinions and idler above referred to will reverse themovements of the rollers causing them to turn back any combed web orsliver then lying between them.

As the cage of the roller motion is moved forward and back, operatingthe detaching rollers, the direction, time and extent of their movementwill depend upon the direction of movement .of the cage of the rollermotion, and upon the time and period of engagement of the pawl with theratchet, and this will depend upon the position of the pawl controllingdisk 25 which permits engagement or disengagement of the pawl withrelation to the ratchet. The relative positions of the pawl controllingdisk and follower during each period of the forward and reversemovements of the detaching rollers is shown diagrammatically in Figs. 8to 11, inclusive. Fig. 8 illustrates the relative positions of the pawlcontrolling disk and follower at the beginning of theforward movement ofthe detaching rollers. The driving disk H is now about to move the cageof the roller motion backward or in an anticlockwise direction. Thefollower is engaging the edge 32 of the pawl controlling disk and thepawl is in engagement with the ratchet. Thereupon as the cage is movedbackward the follower will travel along the edge 32 of the diskpermitting the feed of the detaching rollers until the follower rides up4 onto the edge 3| of the disk thereby throwing out the pawl andpreventing further feed of the detaching rollers. After the followerrides up onto the edge 3| of the disk it will continue its movementalong this edge until the termination of the reverse movement of thecage of the roller motion and will assumea position substantially asshown in Fig. 9. The, feed of the detaching rollers may continue for thewhole or any part of the reverse movement of the cage of the rollermotion and will depend upon the precise adjusted position of the pawlcontrolling disk, the position of the disk controlling the time when therollerrides off the surface 32 onto the surface3| of the disk; .Afterthe cage of the roller motion has concluded its reverse movement thedriving disk will thereupon move the cage in a forward or clockwisedirection, the disk and follower being then substantially in theposition shown inFig. 9. At just about the instant of the beginning ofthis forward motion of the cage the disk will be turned into a positionsubstantially as shown in Fig. 10, the follower then resting on the edge3| ofthe disk and the pawl accordingly being out of engagement with theratchet. Thereupon as the forward motion of the cage continues thefollower will move along the edge 3| of the disk until it rides downonto its'edge 32 permitting engagement between the pawl and ratchet andthereby moving the detaching rollers in a reverse direction, themovement continuing until the termination of the forward movement of thecage when the follower will be left in engagement with the edge 32 ofthe disk and occupying a position substantially as shown in Figl ll. Theextent of the reverse movement of the detaching rollers will depend uponthe precise adjusted position of the pawl controlling disk or, in otherwords, upon the time when the follower will ride onto its edge'32. Asjust described, at the termination of the forward movement of the cageand reverse movement of the detaching rollers, the follower will be leftengaging the edge 32 of the disk and accordingly the pawl in engagementwith the ratchet. Thereupon atjust about the instant that the cage ismoved backward, the follower then being in the position shown in Fig.11, the pawl adjusting disk will be moved back into the position shownin Fig. 8. when the operation will be repeated.

It will accordingly be seen that the time and exact extent of theforward and reverse movements of the detaching rollers for any period ofoperation will depend upon the turning and precise'adjusted position forany interval of time of the pawl controlling disk.

The change in the relative position of the pawl controlling disk and thelocation of said disk at timed intervals is obtained by the eccentric 53and spring 51 in their combined influence upon the sliding carriage 36which, through their engagement with the arm 35, controls the movementand located position of the pawl controlling disk. As the eccentric isturned by the shaft 5| the end portion 54 of the eccentric will beturned to engage the wheel 56 on the carriage whereupon the carriagewill be moved forward moving the'arm 35 into a reverse position as shownon the indicator 63 and moving the pawl controlling disk from a positionas shown in Fig. 10 into the position shown in Fig. 9 preparatory to theimparting of a reverse movement to the detaching rollers as abovedescribed. The extent of such movement of the detaching rollers willdepend upon the distance that the pawl controlling disk is turned asdetermined by the throw of the arm 35 as indicated upon the scale 64 ofthe indicator, the extent of such movement of the arm being determinedby the throw of the forward end portion 54 of the eccentric andadjustments as will later be referred to.

As the forward end portion 54 of the eccentric turns away from the wheel56 on the carriage the spring 51 will act through the carriage to movethe armiinto a delivery position as shown on the indicator, therebymoving the pawl controlling disk from a position as shown in Fig. 11into the position shown in Fig. 8 preparatory to the imparting of adelivery or feed movement to the detaching rollers as above described.The extent of such feed will depend upon the distance that the pawlcontrolling disk is turned, or upon the distance that the arm 35 isturned into its delivery position as indicated upon the scale of theindicator and this is determined by the amount that the spring isallowed to draw back the carriage, the limit of such movement beingdetermined either i by the engagement of the wheel on the carriage withthe end portion 55 of the eccentric, or by the engagement of theadjusting screw 58 on the carriage with the butt 59 forming a stop onthe frame of the machine.

By means of the adjustments the exact and precise extent of movement ofthe arm 35 in the direction of delivery or reversal as shown on theindicator and accordingly the exact andprecise extent of movement of thepawl controlling disk, which measures the extent of feed of thedetaching rollers and the extent of their reverse movement, will beobtained. These adjustments include the adjustable connection 39 betweenthe arm 31 of the carriage and the arm 35, the adjusting screw 41 forshortening or lengthening the arm 31 of the carriage coupled with theclamp stud 45 for locking together the separate parts of this am in anyadjusted position, and the adjusting screw 58 on the carriage which byits engagement with the butt on the frame of the machine acting as astop limits the reverse movement of the carriage as effected by thespring. By connecting the arm 31 of the carriage to the arm 35 at pointsvariably distant from the axial center of the shaft on which this arm ismounted, or by lengthening or shortening the arm 31 of the carriagegreat variety in the extent of movement of the arm 35 on the reversalside of the indicator may be obtained, while the exact extent ofmovement of the arm on the delivery side of the indicator maybe obtainedthrough adjustment of .the screw 58 which engages the butt on the frameacting as a stop. In fact any precise adjustment in the throw of the arm35 as on the delivery and reverse side on the indicator as evidenced byitsscale may be obtained through some one or all the adjustments abovenoted. and accordingly the precise extent of feed of the detachingrollers occurring at properly timed intervals is also obtained, inasmuchas the pawl controlling disk which controls the operation of theserollers is itself controlled by the movement and positioning of the arm35. I

With the mechanism thus provided any vary ing extent of forward andreverse movement may be imparted to the detaching rollers, de pendingupon the character of the staple worked upon. For obtaining the piecingup operation and delivering the combed web the feed of the rollers willprogress so far as to obtain a maximum feed or delivery, at the sametime not so far but that the body of the web will be left in the bite ofthe rear detaching rollers. Consequently on the reverse movement of therollers for returning the web for obtaining the piecing up operation,the fibres in the combed web will not follow the top roller andaccordingly curls in the combed web will be eliminated. The reversemovement of the detaching rollers will only be so far as to properlyeffect the piecing up operation for'obtaining a web of uniform body. Inother words, the reverse movement of the rollers will be so graduated asto make such return of the web that the combed fringe of the lap broughtforward by the nipper for effecting the piecing up operation will beapplied and pieced to the contracted rear end portion of the combed web,which is the contracted rear end portion of the tuft last applied, andwill not be laid to lap onto the body of the web. Consequently therewill be delivered a combed web or sliver having uniformity of body. Allexcess motion in the detaching rollers will be eliminated so preventingwear. Not only is the forward and reverse movement given the detachingrollers a precisely adjusted movement but is obtained by adjustmentinherent in the machine without renewal of replacement of parts and withthe relative extent of movement forward and reverse clearly obvious tothe operator as evidenced by the scale on the indicator.
